Preheat oven to 350 degrees. Spray a 9x13 baking dish with non-stick cooking spray and set aside.

In a large mixing bowl, make cake batter per instructions on back of cake mix box. (I substitute melted butter for the cooking oil.)

Pour batter into baking dish and smooth out.

Layer peaches from pie filling can across the top of cake batter.

Bake per instructions on back of cake mix box until a tooth pick comes out clean in the cake portion.

Allow to cool on a wire rack for 10 minutes. Sprinkle with powdered sugar and enjoy.
